A Continuum Approach to 2d-quantum Gravity for C>1


A Lagrangian continuum model for a string theory with central charge c>1 is formulated by incorporating Weyl and diffeomorphism gauge fixing. In particular the tachyon scattering amplitudes are deduced generalizing the standard c≤1 computation. Despite the remarkable progress of last years in understanding the quantum theory of gravity in 2 dimensional… (More)
